“In 1447 in the Valley of Mexico was so much snow that the population died. The next two years were lost because it froze the grain…” – Dr. Victor Manuel Velasco Herrera
Mexico Should Beware the Little-Ice-Age Cycle
According to research by Dr. Victor Manuel Velasco Herrera of the Institute of Geophysics of the National Autonomous University of Mexico, falling solar radiation indicates that our planet is now entering a mini ice age, a mini ice age that will last between 60 and 80 years.
Dr. Velasco Herrera bases his observation on the fact that many climatic events are cyclical.
“Over the past 400,000 years, there have been extremely cold periods called ice ages, which last on average 100,000 years, as well as hot or interglacial periods lasting about 12,000 years. On our planet the cold periods are extremely long, while the hot periods are very short, “says Dr. Velasco Herrera.
Could be the preamble of the next ice age
“Between one ice age and another we have interglacial phases hot like what we are now but that could be coming to an end because the ice age mini could be the preamble of the next ice age that will last 100,000 years.”
“In this case, we have investigated not only the warm interglacial cycle known as the Holocene and which are 12,000 years old but also the ice ages; we analyzed thousands of years and entered a new stage to examine millions of years to understand more, “said Dr. Velasco Herrera, as reported by a UNAM bulletin.
The researcher created a physical model, called ELSY, which analyzes climate change – both heating and cooling – on a larger scale, including cyclical variations.
Cyclical variations could cause problems in Mexico
For example, Dr. Velasco Herrera found that “in 1447 in the Valley of Mexico was so much snow that the population died. The next two years were lost because it froze the grain and therefore there was a big cost. In 1450 the snow was so excessive that houses collapsed and there was an epidemic of cold that killed many elderly people. In 1451 in Tula, Hidalgo, the snow fell to the knees and in 1454 we had the lake of Tenochtitlan frozen. ” This shows that the great cold of Maunder’s minima was not only in the northern hemisphere but was also felt very much in the southern hemisphere.
These changes have alternated with periods of heat. Between 1618 and 1619 in Puebla the crops and fruits were dry; in 1648 records show the heat “burned” Merida. “There is also documentation of major hurricanes, as occurred in Tlapa, Guerrero, in 1537; The chronicles say that for the winds the trees were uprooted and this only happens in a category four or five of hurricanes,” the researcher said.
“His analysis shows that we are really at the beginning of a mini ice age, which will generally not cause serious problems for countries that have winters with sub-zero temperatures but could be of concern to countries like ours (Mexico) that are very vulnerable to any drop in temperature.”
